July, 1933] Roughage Production in New Hampshire 35 



Hungarian and soybeans furnish an annual hay at the lowest cash 

 expense per acre. Oats and vetch are somewhat higher in cost, and 

 oats and peas the highest of the three most important annual hay crops. 

 The extra labor required for fitting the Hungarian-soybean land for 

 permanent hay seeding is apparently an advantage in increasing the 

 yield of permanent hay. Hungarian and soybeans reduce the peak 

 labor load by extending the harvest period. Oats in combination some- 

 times interfere with early hay harvest, but the farmer's possession of 

 equipment and experience for handling oats place it first as an annual 

 hay. 



Silage required 64.2 man hours per acre and 5.5 hours per ton and 

 cost with assumed rates for labor $4.52 per ton to produce. No charge 

 was made for land, buildings or manure. The cash costs, omitting la- 

 bor and machinery use, were $11.01 per acre or 94 cents per ton. 



Hay required 11.3 man hours per acre and 7.7 hours per ton and 

 cost with assumed rates for labor $8.45 per acre and $5.71 per ton. The 

 cash costs were $2.94 per acre and $1.99 per ton. 



Labor-saving methods on some farms have reduced the labor on 

 corn silage 21.5 per cent., and on hay 26.7 per cent.
